The primary objective of this effort is to develop appropriate signal models and algorithms for behind-the-wall stationary and moving target localization and building layout mapping within the CS framework. A secondary objective is to enable enhanced imaging and detection of low-signature buried targets in forward-looking ground penetrating radar applications. To this end, we have made the following main contributions 1 Mitigation of clutter and stationary targets through conversion of populated scenes to sparse scenes based on Moving Target Indication techniques 2 Effective front wall clutter suppression under reduced data volume for detection of stationary targets behind walls 3 Exploitation of the rich multipath nature of the indoor environment in conjunction with compressive sensing for improved stationary target detection and localization in sparse scene scenarios 4 Enhanced detection and tracking of moving targets through multipath exploitation 5 Utilization of prior information of building construction practices for determining the building layout under compressive sensing 6 Robust multipath exploitation based target localization approaches through dictionary learning in the presence of inaccuracies in knowledge of building layout 7 Effective reconstruction of target scene using a distributed network of through-the-wall radar units in the presence of multipath 8 Exploitation of target spatial extent for high-resolution through-the-wall radar imaging under the sparse reconstruction framework 9 Multi-view target detection schemes for forward-looking ground penetrating radar operating at close-to grazing angles and 10 Coherence factor based rough surface clutter suppression in forward-looking ground penetrating radar applications.
